Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483648, here are decompositions:

71 + 31483577 = 31483648
101 + 31483547 = 31483648
179 + 31483469 = 31483648
191 + 31483457 = 31483648
257 + 31483391 = 31483648
419 + 31483229 = 31483648
431 + 31483217 = 31483648
479 + 31483169 = 31483648

Showing the first eight; more decompositions exist.
